reason will be described only in a general way her i Machine frameworkThe machine chosen to illustrate the present invention is similar inappearance to the machine disclosed in FIG, 1 of the co-pe ndingapplication, Serial No. 255,870, now Patent No. 2,722,887, referred toabove, and comprises a ffamework for supporting the mechanism of themachine,- including 'a right frame 20 (FIG. 4)and a similar left frame(not shown), said main frames being secured in properspacedapartrelatio'n to each other on a machine base plate in turn secured tothe. top-surfaceof a drawer cabinet, in which is mounted a cash drawer.The base plate and drawer cabinet are not disclosed herein, but aresimilar to those disclosed in the application referred to above. Themain frames are further secured in proper spaced-apart relation to eachother by various cross frames, rods and bars, as is the usual practice.

of a small electric motor (not shown), located in the back of themachine. However, a hand crank is pro-, videdfor operating the machineunder unusual conditions, such: as the absence of electrical current.

Keyboard The keyboard includes a cover plate 21' (FIG. 1) having anumber of apertures therein, through which exend five rows ofdenominational amount keys 22. and one row of transaction keys 23-. Akey release lever 24, extending through an aperture in the plate 21(F'IG..1) is provided to release any depressed amount or transactionkeys, when necessary or desirable. The amount keys and the transactionkeys are of flexible construction, whereby depression of an amount ortransaction key re leases any key proviously depressed in the same row.

A motor bar 25, which extends through an aperture in plate 21, isprovided for initiating machine operation.

A control 'slide 26 is movable to various positions to control Adding,Reading and-Resetting functions, and also.

has a position in which the mechanism of the machine Patented Sept. 26,1961 1 aooress member '47 tothe right to assist restoring the member 47in this direction. r i Y Means is provided for normally latching themember 47 (FIGS. and 6) against lefthand movement to aline the itemtotalizer with the actuators, said latching means being renderedineffective by the control slide 26 when it is in Register or Addingposition.

An arm 68 (FIG. 6) pivoted on the stud 67 is urged counter-clockwise bya spring 69 until a projection thereon engages a stud.70 on theauxiliary frame. A stud 71 on the arm 68 extends in front of a hook. 72on the member 47, and prevents any unintentional movement of said member47 to the left. Arm 68 is rocked clockwise by high portion 73 of acontrol member 74, which portion 73 engages a stud 75 on the arm 68 whenthe control slide 26 is in Adding position. Arm 6 8 is similarly rockedclockwise by high portion 76 of member 74 when the control slide is inRegister position. Control member 74 is pinned to shaft 87, which isdifferentially positioned by the control slide 26.

The means for shifting the member 47 to'the left from its normalposition and back to its normal position is shown in FIG. 6, and willnow be described. Freely mounted on the stud 77, carried by the lowerend of a lever 78, is a lever 79, which has on its upper end a stud 80,which is adapted to selectively engage vertical surfaces 81 and 82 onthe member 47, to shift the member; respectively, to the left and to theright. The lever carries near its lower end a stud 83, which is adaptedto coact witha control segment 84.

The lever 78 is pivotally mounted on a stud 85 on the main frame 20.During each operation of the machine, a pair of cams (not shown) areeffective through a cam lever (not shown), and link 86 to impart to thelever 78.

first a clockwise movement from its home or normal position, thenacounter-clockwise movement past its home position, and movement back toits home position.

As the lever 78 partakes of these movements, the stud 77 in the lowerend thereof will move to the left, then to the right, and finally backto the left, andwill tend to move the lever 79 in these directions. Ifthe stud 83 in the lower end of lever 79 is blocked against movement ineither direction, the stud 77 will cause the lever 79 to pivot about thestud 8 3 and be effective through the engagement of stud 80in the upperend of the lever 79 with the surfaces 81 and 82 on the member 47, toshift the member 47 and the slide 40 to the left and right. However, ifthe member 47 has previously been shifted to the left, and the rear endthereofhas dropped down in front of the stud 48, this driving movementof lever 79 will be ineffective to further shift the member 47. If thestud 83 in-the lower end of lever 79 is free to move, then the stud 77,in its movements to the'lefit and right will cause the lever 79'tooperate idly without imparting any shifting movement to the member 47.The blocking of the movement of stud 83 is eifected by the controlsegment 84, which is set by the control slide 26.

Control segment 84 is pinned to shaft 87, which is differentiallypositioned by the control slide 26. A cutaway part of this controlsegment provides an arcuate surface 88 which blocks movement .of thestud 83 to the right in all positions of the control segment, provides asurface 89 which blocks movement of stud 83 to the left when the controlslide is in Register position, and also provides a control surface 90which blocks movement of stud 83 to the left when the control slide isin Adding position. i

It will be noted that in all operations, when the control slide 26 is inRegister positiom'movement of stud 83 (FIG. 6) in both right andleftdirections is blocked by surfaces 88 and 89, respectively.Similarly, in all operations when the control slide 26 is in Addingposition, movement of stud 83 in both right and left directions isblocked by surfaces 88 and 90, respectively. This results in bothrightand left movement of stud 80 6 in all such operations. However, inany operation in which it is desired to shift the member 47 to the left,to shift the item totalizer 28 into alinement with the amount actuators3 1, arm 61 will, by contact of stud .65 thereon with a low portion ofthe periphery of control segment 64, permit member 47 to drop into aposition such that stud 80 will not engage surface 82, and thereforewill not shift member 47 during movement of stud 80 to the right. Also,it will be noted that in machine operation the stud 80 is shifted firstto the left and then to the right, so that in any operation in which itis desired to shift the member 47 to the right to shift the grouptotalizers 29 into alinement with the amount actuators 81, the initialshifting of the member 47 to the left will not afiect the final desiredresult, since arm 61 will, by con; tact of stud thereon with the highportion of the periphery of control segment 64, retain member 47 in suchposition that the stud in moving to the right after completing itsleftward movement, will engage surface 82 of member 47, and shift themember 47 to the right. a

The shifting of the totalizers to selectively aline either the item orgroup totalizer with the actuator segments 31 is therefore jointlycontrolled from the control slide 26 and the transaction keys 23',according to the particular operation performed.

Automatic item transaction selection mechanism As has been stated, thepresent machine is equipped with both an item totalizer and a grouptotalizer. Novel means is provided for alining the item totalizer withthe amount actuators automatically, when amount keys are depressed andthe machine operated without depression of any of the keys in thetransaction bank.

Each bank or denominational row of amount keys is provided with a plate(FIGS. 3 and 9) which is slotted to cooperate with cam surfaces 96 onstems 97 of amount keys 22. The forward end of plate 95 under lies arounded nose 98 on a zero stop pawl 99 freeon the shaft 100 journaled inthe main frames. Pawl 99 is normally urged in a clockwise direction byspring 101. A tooth 102 on the zero stop pawl 99 is adapted to coactwith a bent-over ear 103 on a differential slide 104 to retain saidslide in zero or normal position during machine operation, in the eventno amount key in that bank is depressed. The forward end of plate 95also underlies the rounded nose on a segment 105 free on the shaft 100.A finger 106 on segment 105 is adapted to coact with the bail of a yoke'107 (FIGS. 2 and 3) free on shaft 100. Also free on shaft 100, andconstructed to embrace the hail of yoke 107 and to move with said yokeis an arm 108. Arm 108 is pivotally connected to one end of a link 10 9,which is pivotally connected at its other end to an arm 110 (FIG. 2) ofa yoke 111', free on a shaft 112, which is journaled in the main frames.Yoke 11 1 also includes a bail 1 13 and, an arm 1'14, offsetapproximately ninety degrees from the arm 110, to which link 109 isconnected. Mounted on the arm 114 of yoke 111 is a stud 115 adapted tocoact with a cam surface 116 on a segment 117 free on the shaft 100.Segment 117 is normally urged in a counter-clockwise direction by aspring 11 8. Free on shaft 100 is a zero stop pawl 119, having a tooth120 which is adapted to coact with a bent-over ear 12.1 on a transactiondifferential slide or control member 122, to retain said slide in zeroor normal position during-machine operation in the event no key in thetransaction bank is depressed. Mounted on pawl 119 is a stud 125, towhich one end of a spring 1 26 is secured. The other end of spring 126is secured to a stud 127 mounted on segment 117. There is thus provideda flexible connection between segment .1'17. and pawl 119, whereby pawl119 will normally move with segment 117 when the segment is rocked in aclockwise direction. However, it will be noted that pawl -119 may. movein a counter-clockwise direction independently of segment 117. r

' lltwillbe 'seen'that when an amount key is depressed in any amountbank, the plate 95 is'sbifted forwardly or-to the left, as viewed inFIG."3, releasing zero stop pawl 99 in the amount bank; The plate 95, inshifting forwardly, also rocks the segment 105 in a counterclockwisedirection. Finger 106 on segment 105 coacts with the bail of yoke 107,rocking the yoke counterclockwise. When yoke 107 is rockedcounterclockwise, a counter-clockwise motion will be imparted to yoke111 by link .109, and yoke 111,'through arm 114 and stud11-5, will inturn impart a clockwise motion to seg ment 117. Since pawl 119 isflexibly connected to segment 1117, it also will be rocked clockwise,positioning tooth :1 20in the pathof car 121 on slide 122.

IWhenmachine operation is initiated by depression of motor bar 25,retention of the transaction differential slide 122 in zero positioncauses control segmcnt64 (FIG. 6) tube positioned by thetransaction'diiferential mechanism with its zero position opposite stud65. It will be recalled that there is a low portion on the periphery ofcontrol segment 64 at the"zero position of its upper control surface.Positioning of this low portion opposite the stud 65 will permit the arm61 to drop downwardly when member .47 is shifted to the left, and willcausethe member 47 to beretained in this shifted position by theengagement ofits rear edge with the stud is moved out of coactingrelationship .with earllZl transaction dilferential'sli'de 122.v

Automatic sub-total mechanism I Novel means is herein provided forinitiating a sub.-

Total operation of the machine merely by depressing the motor bar whenone or more item amounts have previously been entered into the machine.

Mounted on the keyboard assembly isa bracket 14.0 (FIG. 2) to which issecured a second bracket 1 41. A portion of bracket 141 is bent overto'form an car 142 inv which ismounted a stud 143. A stop member 144having a linger 145 isfree .on stud 143. A spring 147 extends between astud 146 in the member 144 and. a

48. As previously explained, shiftingof member 47 to the leftpositionsthe item totalizer in alinement with the amount actuators. V V

The transaction bank of keys is provided with a control-plate 128 (FIG.2)'which isslotted to cooperate with cam surfaces 129 on stems 130 ofthe transaction keys 23. When-a transaction key is depressedthe plate128, will be moved forwardly or to the left, as viewed in FIG. 2, andwill contact a surface 131 on pawl 119.

Since the connection between pawl 119 and segment 117 is flexible,the'pawl 119 may be rocked counter-clockwise by plate 128, to displacetooth 120 from the path of car 12 1. of the slide 122, thus permittingmovement of slide 122 .upon machine operation, even though segment 117has previously been rocked clockwise by stud 115 0 arm 114. Q

' Thus it will be seen that the automatic item transaction selectionmechanism is rendered effective when amount keys are depressed, and isrendered inelfective by depression of any of the keys in the transactionbank.

Means is provided, effective near the end of each cycle of machineoperation, to rock the tooth 120 of arm 119 (FIG. 2) out of the path ofcar 121 on transaction ditferential'slide 122, in the event that tooth120 has been engaged with car 121 during the operation. This includesmechanism not shown but fully disclosed in the above cited patent toCarey et 211. (see particularly FIGS. 15, 39, and of said patent) forreleasing all depressed keys, which in turn permits'plate 95 to returnrear- 'vi'ia'rdly a .sufiicient distance that spring 101 will urge zerostop pawl 99 in a clockwise direction into the path of ear 103 of amount"ditferential slide 1114. Clockwise movement ofpawl 99will betransmitted to segment 105 by means of a projection 132 on said pawl 99.coacting with a stud 133 on, segment 105. Clockwise movement of segment105 moves'finger 1% out of engagement with yoke 107 and permits a spring(not shown) which is connected to yoke'107 and to the side frame 20 torock transaction differential slide 122.

free to be moved in a counter-clockwise direction by spring 118 and inthus moving, rocks tooth of zero stop pawl 119 out of the path of ear1210f transaction difierential slide 122 by virtueof the coactionbetween cam surface 116 on segment 117 and stud on pawl 119. Thus itwill be seen that at the end ofeach cycle of machine operation tooth 120of zero stop pawl 1 19 43, rotates counter-clockwise with said shaft.25'

stud 148 in an arm 149, said arm being secured to shaft 43. Spring 147thus provides a fiexibleconnect-iou between stop member 14.4 and arm149. Free on'stud 14.8 is a roller 150 adapted to coact with a camsurface 151 on stop member 144. V

Inmachine operation, as has been previously explained, shaft .43 isrotated counter-clockwise by arm 45 (FIG. 5) Whenever the item totalizeris shifted into alinement with the amount actuators. Arm 149, beingsecured to shaft Due to the spring connection 147'between arm 1.49 andstop member .144, stop member 144 is rotated clockwise uponcounter-clockwise rotation of shaft 43, thus positioning finger 145 inthe path of an car 152 on the transaction differential slide 122. VTherefore when item amounts have previously been enteredin the machine,and a sub-total of these amounts is desired,motor bar 25 is depressed.Upon initiation of' mac hine operation by depression of the motor bar,the transaction differential slide 122 is moved rearwardly or to theright as viewed in FIG. 2, until ear l52en gagc's finger.145,the tooth120 having been rocked out ofthe path of car 121 of the transactiondifferential slide 122 near the end of the previous machine operation,ashas 1 been previously explained. This movement of the trans actiondifferential slide causes the transaction differential chine for aSub-Total operation.

Finger 145 will remain in position to engage ear 152 on transactiondiflerential slide .122 so long as the item totalizer 28 is alined withthe amount actuators 31. "Upon shifting of the item totali'zer out ofalinement with the amount actuators, shaft 43 will be rotated clockwise.Clockwise rotation of shaft 43 and therefore of arm 149, causes rollerto engage cam surface 151 on stop member 144 ,to rock said stop membercounter-clockwise, which moves finger 145 out of the path of car 152 onAutomatic no sale mechanism Novel means is herein'provided forinitiating a No Sale operation merely by depressing the motor bar whenthe machine has been conditioned by its previous operationso that thegroup totalizer is in alinement with'the amount actuators. V V

In a No Sale transaction, the transaction differential slide 122 travelsfull distance rearwardly, or to the right as viewed in FIGS. 2 to 9, orNo Sale position; This position is determined by a projection 153 on thetransaction differential slide 122 coming in contact with a square stud1154.. Stud 15-4 is mounted on a partition plate (not shown) positionedbetween the transaction ditfera ential slide 122 and the amount.diiferential slide im-' mediately adjacent it.

Upon initiation of machine operation, by depression u of the motor bar25, the transaction differential slide 122 is moved rearwardly or to theright as viewed in FIG.'.2.

., until projection-153 engages "stud-.1154. This-movement of the slide122 causes the transaction diiferential mecha-f stud .65 of :arm 1,61and conditions the machine for. a

saleoperation.

JIt'will be seen that in order. for :a No Sale operation .to take placeupon depressionof the motor bar .25, the

transaction differential slide .122 must :be -free to move :to'

.;the :full extent of its travel. Therefore no amount keys 22 may bedepressed, since,.as previously explaineirthis would :move :tooth 1200fstop pawl 119 (FIG. "2) into sthe path of ear 121 of slide 122 and:rthereby retain the slide 122 against movement. Similarly notransaction key 23 .may' bedepressed since. depression of any of theseikeys will move the lower end ,of key stem E130 .of'the' .depressed keyinto the path of its respective ear on the slide 122 and thus preventthe slide from moving to the full-extent of its travel. Lastly theprevious operation of. the machine must ghave been one in which :thegroup .totalizer 29 rather than the item totalizer 28, was shifted intoor remained in alinement with the amount actuators 31, since, as.previouslyexplained, when the item totalizer 28 is in alinernent withthe amount actuators 31, the :finger 145-(F.IG. 2) of stop :member 2144.is positioned in the path .of'ear 1520f slide 122, to prevent slide 122from moving past 8, or Sub-Total, iposit'ion. Lacking means for certain0f;the' transaction keys ,NQvel-mcansis herein provided for locking.certain of markers in the tran c ion bank, nam ly the :Paid out, Ch ge,'Received'ton Account and Cash Iotal keys, a gainst depression exceptwhen {the item 'totalizer has been shifted int 'a ne c itht e amo nt auato s- The stem of each of the Paid Out, Charge, Received .onAccount.and Cash Totalikeys in theqtransaction hankhas' a cam surface 161(P1658) which is adapted .to eooperate with a surface 1620f a $1.01: ina.dete nt 1563 J 1.Q medi 1 nSaction k y row. .At its .torward endidctent 163 is provided .with la hook 164 which engages a stud 165'mounted on an .arm 166 ,which-is secured .to a

Counter-clockwise rocking.of shaft 43 :andof arm 181 (FIG. 8) 'will shift .link 21757 01 wardly,or to the left as viewed in .8, causing the surface 178 to engage thestud 174, and rock ithe lever .171' in a clockwise direction. This moves.hook 175 of "lever 171 out of blocking relationship :with :finger 1169of arm "168; Therefore, as long as :the item ZtOtHHZE/I' 28 remains inalinement with the amount actuators 131,- surface 178 of link 1 77will-retain lever 171 -in .a .position wherein 11001:175 of'said leverdoes not block counter-clockwise rocking of ,shaft 167. Thus it is.evident that the Paid Out, zCharge, Received on Account and .Cash Totalkeys are blocked against depression by .coaction of the finger i169 andthe hook 175 at all times,

, except when the item'totalizer 28 is in ,alinement with the amountactuators 3.1.

In addition to the abovedescribed locking means, an interlock isprovided between amount keys 22 and Paid :Out, Charge, Received onAccount and Cash Totaltransaction keys, whereby when any amount key 22is depressed, the aforementioned transaction keys are locked againstdepression, and conversely when any of the aforementioned transactionkeys have been depressed, the amount keys are locked against depression.This interlock is of the same type as the interlock disclosed in thepatent-cited=above to Carey et al. which acts in that patent to lock=the"' Iotal,' Sub-Total or No Sale keys'against depression, if amountkeys are depressed, and conversely acts to lock the amount keys againstdepression if the Total, Sub-Total or No Sale keys are depressed. Thisinterlock is shown particularly in FIG. 38 of the above cited patent;

As in the case of a Paid Outtransaction this total will "be cleared from the item totalizer butwillnot be entered into the group totalizer since it does not representan similar procedure is followed to cause the machine to indicate andprint the total of items entered as alReceived jonAccount transaction.In this case however, when the item totalizer is cleared the totalistransferred'to the Pi :group totalizer since this total represents anactual amount received. A

The sequence or operationsiin'a Cash, Total operation is similar tothat: in a Received onAccount transaction.

tion is out'of the path it v l of movement her; and means connected tosaid shifting means, adapted to move the stop member from saidsecond'position:to said first position whenlthe. shifting means shifts'theitem totalizerinto'alinement with the actuators, and adapted V tomove the stop member from said first position to said 7 second positionwhen the shifting means shifts'the group It ,will therefore-be seen thatthe .Paid Out, Charge 1 and Received on Account keys'as well as the CashTotal -key etfect total-taking operations'. For this reason the Tlmutual interlockbet'ween theamount keys and the Paid Out, Charge,Received. on Account and CashTotal keys is provided so that no amountkeys can be depressed when a total is being taken and so that thesetransaction keys cannot be depressed, in conjunction with amount .keys.The lockingme'ans which prevents the depression of these transactionkeys, except when an amount has previously been entered in thevmachine,is provided to insure thatsaid keys will not be employed by anoperaftorjmei'ely to cause opening of the cash' drawer since such anoperation is properly a No Sale transaction and I should be indicated assuch. 7
